' Application medium 12,

Toall whom it may concern:

Be it known'that we, CLARENCE C. J OHN- soN, a resident of Mount Vernon, Westchester county, State of New York, and RICHARD M. HOPKINS, a resident of Rutherford, Bergen county, State of New Jersey, both citi- Zens of the United States of America, have invented 'a Registry System and Register Therefor, of which the following is a specification:

@ur invention relates to improvements in watchmen s registry systems, by which term is meant systems in which the visits of watchmen to certain stations which they are supposed to visit regularly, are registered, and embodies improvements in the system for the same purpose set forth in the application of C. C. Johnson, Sr. No. 209,279, filed Dec. 28, 1917. According to the said Johnson system, the watchmen is provided with a portable register having registry mechanism adapted to be actuated by a pushbutton or other suitable device which the watchman may actuate each time he reaches a station which he is supposed to visit; but this registry mechanism is normally locked, and cannot be actuated, except and until the Watchman applies his register to a key device, or conditioning device, of which there is one at each station to be visited. When the register has been so applied to a key device (preferably, means are provided Whereby'on each occasion only one particular-key device may be so used) then, and only then, the watchman may actuate the registry mechanism and so register his visit to that particular station. The several key devices are preferably provided with means whereby they are differentiated one from another, and the mechanism of the register is such that actuation of the registering mechanism at one station conditions that mechanism for-release upon application to the next:

key device of the series, and upon applicaion to said next key device only. In this way the watchmen is compelled to visit the several stations in regular order, and cannot continue to actuate his registering mechanism if he omit any staton in making his tour, or if he visit stations out of order. When the watchman reaches the end of a tour he may connect suitable transmitting mechanism within his register to a suitable circuit, or, alternatively, may connect his Specification of Letters Patent.

register to suitable stationary transmitting mechanism, and may then send through such circuit a signal indicating that he has completed the tour. In this way it is rendered unnecessary for the watchman to signal to the central station separately for each visit to each of his stations; one signal sent at the conclusion of each tour showing that he has visited ali of the stations in'that tour.

The object of our present invention is to improve and simplify the mechanism of such systems, particularly the registers-and signal-transmitting means thereof; and our invention comprises an improved and simplified register, also an improved combined keydevlce and transmitter by means of which, when the register (properly conditioned by regular application to previous key-devices) has been applied thereto, the required signal may be sent. Other features of our invention will be pointed out hereafter.

We will now proceed to describe our invention with reference to the accompanying drawings, illustrating one embodiment of the improved register and of the improved combined key-device and transmitter, and

will then point out the novel features in claims. In the said drawings:

Figure 1 is a side elevation of the register, aportion of one of its parts being broken away; Fig. 2 shows an end elevation of the register, viz., the end at the left of Fig. 1; Fig. 3 shows a longitudinal central section of the register; Fig. 4 a transverse section of the register on the line 44 of Fig. 3; Figs. 5, 6 and 7 are transverse sections of the register on the lines 5-5, 66, and 7-7 respectively, of Fig. 3; Fig. 8 is a detail perspective view of the central hollow spindle of the register, with one of the tumbler-carriers mounted thereon; Fig. 9' is a detail perspective elevation of one of the tumbler-carriers; and lug. 10 is a diagram illustrative of the system.

Fig. 11 shows a side elevation of one of the key-devices or conditioning devices, Fig. 12 a front elevation thereof, Fig. 13 a rear elevation thereof, Fig. 14 a central longitudinal section thereof, and Fig. 15 a transverse section on the line 1515 of Fi 11; Fig. 16 is a fragmentary perspective elevation of certain portions of the key-device, illustrating the fall-apart feature thereof.

Fig. 17 shows a front elevation of the instrument having been broken awa combined key-device and transmitter, lo-

cated customarilyat the end of the tour, the

greater portion of the inclosing case of tltie show the interior mechanism; Fig. 18 s ows a top view of said mechanism, and Fi 19- an end elevation, looking. from the le t of Figs. 17 and 18.the register being also shown partly inserted, in Fig. 19; Figs. 20 and 21 are diagrams, similar to Fig-.10, illustrating how the connections in the contact combina-' 'tion associated with the transmitter may be 1 varied to make difficult tampering withthe somewhat of the appearance of a key of massive proportions, but is not in fact a key,

having registering mechanism within it, to-' gether with means for actuating that mechanism. Externally, the principal visible parts of the register are, a handle portion 21, and a series of tumbler-carriers 22. Internally, the register comprises a tubular mem ber 23, (Fig. 8), the rear portion of which is provided with longitudinal slots 24, for a purpose hereafter made apparent, while in the front portion are tumbler-holes 25. The

"tumbler-carriers,- 22', are mounted on this member 23, and each comprises a ring-.portion 22, and a lug 22 the latter bored radially for the reception of a pin-tumbler 26 and its actuating spring, 26. The pintumblers, of course, are adapted to engage the tumbler-holes 25 of the tubular member 23, but normally are restrained from passing completely through said holes by aslidable sleeve 27,-mounted to slide longitudinally within thev tubular member 23, but normally pressed out by a spring 28; projections 27 of this sleeve work in the slots 24 of tubular member 23.

Surrounding the'handle-end of the tubular member 23 is another sleeve 29; and slidably mounted upon member 29 is still a further sleeve 30, adapted to retreat into the handle 21,.but normally pressed out by a spring 31. Sleeve 30 is slotted to embrace, and to permit the radial projection of, the lugs of the tumbler-carriers 22. Normally, sleeve 30 holds all of these lugs in-line; but if pressed back into the handle, then so far as sleeve 30 is concerned the tumbler-carriers may be rotated with respect to the body portion of the register, though such rotation is prevented normally by engagement of the pin-tumblers with the holes of tubular member 23.

A screw-coupling 32 connects handle 21' to the tubular member 23; and a locking in 33 connects 29 and 32. The tubular mem r or sleeve 23 constitutes a tumbler-engaging member,,as will be seen, and is so termed-in certain of the following claims. Said member 23, in connection" with the handle 21 by tering his instrument has .fro

which it ma be rotated, theconnection between'sai members, constitutes the roguetumb or carrying means, such as members 22, is or arenot-necessarily located, outside of-sleeve 23, nor is member 23 necessarily a sleeve. The fundamtntals, in a re 'ster such.

as this, are, registering means an tumblercarrying means, the latter having yieldable tumblers and the former having sockets adapted to receive such tumblers, the registering means and the tumbler-ca ing means being movable relatively, and their arrangement being such that suitable key devices may cause the disengagement-of the tumblers m'the registering means. Obviously, nu-

merous constructions embodying such fundamentals are possible of which constructions that illustrated in figs. 1 to 9 inclusive is one only; all, however, being within our invention.

Referring now to Figs. 11110 15 inclusive, showing one form of key-device" or condimeans of the register. Of course, the

tioning-device-such as may be -used with the particular construction of register'above described: 41 designates the base of this keydevice, adapted to be secured to .a wall or 7 other support, and 42 the shell or casing, and 43 a central tumbler-carrier, having sockets at suitably-spaced intervals for spring-pressed pin tumblers 44, normally retained by a suitably-perforated sleeve 45. The shell 42 has a slide-way 46 to receive the tumbler-carrying lugs 22*. of the register, and the diameter of the tumbler-earner 43 and sleeve 45 are such that if the register be inserted into the shell 42, with its lugs 22 in the way 46, as the register is pressed in the sleeve 27 of the register is pressed back against the action of its spring 28, so enabling the tumblers 44 of the key-device to press back to the parting line'between tumbler-engaging member 23 and the tumbler-carriers 22 all of the tumblers 26 of the register then in engagement with member 23; so freeing member 23 for rotation with respect to the tumbler-carriers. Of

course, such freeing of the tumbler-engaging member 23 for rotation will occur only in case the arrangement of tumblers 44 of the key-device corresponds to the arrangement rangement of tumblers 26 in engagement with the member 23; this being determined by the arrangement of perforations in each row of such perforations of member 23, the

arrangement of perforations of such rows being in each case different from the arrangement in the other rows. consequentllyzi At the same time that the sleeve 27 of the.

register is pressed back, as describedebove, the outer sleeve 30 of the register is also pressed back as a result of the engagement of the end of said sleeve 30 with the side walls of the way 46 of the shell 42; but the 1 sides of this way hold all at the tumbler carriers 22 in line, so long as said tumbler carriers are within the way.

The manner of operating the register at the various key-stations will now be apparent. Supposing the register to be set for application to the first hey-device of the series, the register is inserted into the casing of first key-device, and pressed in; the

sleeve 27 of the register yielding to permit engagement of the tumblers a l of the keydevice with the tumblers 26 of the register.

Since the tumblers at are yieldinglymount ed on springs, and since they are polnted at the top, they yield to perm t sleeve 23'to pass over them, and then sprlng up agaln to engage and press back the tumblers 26 of the register. The register 1s provided, at ts front end, with fins 34 which engage wlth notches in the front of the shell of the keys device, thus insuring accurate presentation of the register to the key-device.

The register having been pressed home to the full distance possible, its handle is now turned (to the right, in the construct1on shown) as far as it will go; engagement of notches 35 in the front end of member 23 with webs 48 of the key-device determining the maximum extent of this rotation. This rotation of the sleeve 23 brings a new row of its perforations opposite the tumblers 26 (for the tumbler-carriers 22, during this rotation of the registering device, have been held stationary by the right side of the slideway 46 of the key-device), and therefore tumblers 26 corresponding to this new row of perforations will enter such perforations immediately, or as the register is withdrawn from the key-device. Thereby the register is set for engagement with the second keydevice of the series, and with that second key-device only; because, as previously explained, no other key-device of the series will have'a combination of tumblers such as will release the sleeve 23 for further registration. In a word, the watchman, in making his round, must visit the various stations in proper order, operating his register at each; and if he fail to visit a particular station, or fail to operate the register properly at each station, he cannot operate his register at any further station of the series.

As previously explained, it is intended that the watchman, during his round, shall at some one station at least transmit a characteristic signal to some central ofiice or point from which supervision is exercised or at which a record is made, of his signals; thereby, in effect, registration of the Watch mans visits to the several stations is transferred from the register to the central station, It has not been thought desirable to complicate the register with signal transmitting mechanism, for the register itself; should be as simple and compact as possible; Therefore, at one or more key-stations of the serles, transmitting mechanism is provided; also, and for a reason stated hereafter, a contact combination operated by the operation of the register is also provided at such transmitting station. Commonly, such a tran mitting arrangement is provided at the last station of the series; but other transmitting stations may also be provided; for example, at the start of the series (so causing the watchman to give a starting signal, when he starts his round) and at some intermediate station, so giving an intermediate check upon the movements of the watchman. Such a transmitting station, comprising a .key-device, transmitting means, and a conmounted in a bridge 50, and contactdevices a-f each arranged to be actuated by depression of the corresponding plunger of series 49. Some of these contact devices a-f may be single, and some double, as indicated in Figs. 10, 20 and 21; and, as will be seen by comparison of these Figs. 10, 20 and 21, the arrangement of the single and double contact devices may be different at difi'erent stations; a wide range of contact permutations being thus provided. The tops of the plungers Mi -49 are rounded, so that as the register is inserted in the usual manner, these plungers will yield successively. The case of the key-device, instead of having a slide-way 46 which prevents lateral movement of all of the tumbler-carriers of the register, has a series of Wards 51 (which may be arranged selectively) whereby when the register is turned on the key-device, some of the. tumbler-carriers 22 are permitted to turn with it, while others are held against turning.

For operating the contact combination a -f, certain on, it may be, all, of the tumbler -44-45, there is a signal transmitter 52,

which may be of anyof the familiar and suitable types. As shown, it is of the ordinary spring-driven type, having a winding handle 53 and a double break-wheel 5455, one member of thisdouble break-wheel being, ordinarily, a line-circuit wheel, while the other is, ordinarily, a ground-circuit wheel; the transmitter being arranged, therefore, for McCulloh operation. Suitable contact pens 56 and 57 are arranged to coact with break-wheels 54 and 55 respectively.

In the diagrams, Figs. 10,20 and 21, for clearness of illustration these break-wheels are shown as of difierent diameters; but it will be understood that in practice this is' not usually the case.

Referring now to Fig. 10, as showing one possible contact arrangement, 58 and; 5 9

' designate binding. posts for incoming and outgoing line circuit conductors, and 60 designates a bindin -post for a ground connection. From binding post- 58 a conductor 61 leads to the middle member of contact device f; and from the lowerspring of this contact device f a conductor 62 leads to the middle member of contact device 6; and from the lower s ring of contact device I) a conductor 63 lea s to pen 56, and thence to break wheel 54, and thence to line binding post 59. The circuit thus traced would be broken and completed, alternately, by rotation of break wheel 54, except that it is bridged and rendered inoperative normally, by a shunt connection fromthe middle contact member of 7, through 64 to the middle contact member of e, and through the lower member of e and'65- to the upper member of e, thence through 66 and 67 to the break wheel 54 and so to binding post 59. It will be seen that this shunt may be broken and the transmitting circuit rendered operative by moving the middle member of contact device e-to a position intermediate both of its contact springs, provided contact be not closed between the middle and upper members of contact device f, or at contactdevice (Z. The middle member ofqcontactdevice- 6. may be brought to such middle position by means of a recess 36 coming op osite the? plunger 46 of contact device .6, t e adjustment of the contact members of this contact}.

device being such, for the particular ar-g ll rangement of circuits of 1( that .the leave Tree, with respect to member 23, those Similarly, there is a ground circuit from binding post 58 through the circuit previously traced to break wheel 54, also from binding post 59 direct tobreak wheel'54, thence to break wheel- 55', and (when pen 57 is in contact with a tooth'of break wheel 55) through en 57 and conductor 68 to contact device 0 where normally the circuit is open) thence through conductor 69 to contact device a, and thence to binding post 60 and to ground. In order that this ground co'nriec tion may be operative, both contacts a and 0 must be closed.

While to a certain extent the arrangement of contacts in contact devices af is controlled by the. fact that in the operation of inserting the register the line circuit and the shunt 67 must not be broken, nor must the 'ground connection be closed, yet obviously the arran ement shown offers a high degree of protection, both because the arrangement is so complicated that any attempt to tamper with the contact device by a person not thoroughly familiar with the connections is almost certain to render the transmitting circuit inoperative, and also because interchanging of the contact devices is possible to ahigh degree, permitting diflerent transmitting stations to have widely different contact arrangements. Thus, comparing Fig. 20 and Fig. 10, contact device f of Fig. 20 performs the function of contact device 0 of ig. 10 contact device'e of Fig. 20' erforms the function of contact device f of ig. 10, contact device-d of Fig. 20 performs the function of contact device 6 of Fig. 10, contact device 0 of Fig. 20 'erforms the function of contact device of F i 10; etc. Similarly, inthe arrangement of ig. 21 the functions of various of the contact devices have been interchanged, as compared with the functions of those contact devices in the arrangement of Fig. 10. It is believed to be unnecessary to trace all of the circuits in full in these figures, as the purposes of the complete contact arrangements are the same in all cases, and the variations shown are I only three of various possible, all of which it is within the ability of a person skilledin the-artto make, once acquainted with the requirements, as stated above.

As will be obvious, the arrangementof 'mblers 44 at the key station preceding a transmitting station should be such as to tumbler carriers 22 which are to be held against movement when the register is operated. at the transmitting station. After the register has been operated at thattransmitting station, and before the register is withdrawn, the watchman turns the handle of the transmitter, so causing that transmitter to operate. 'The break Wheels of the transmitter are provided with a pin 70 (shown in dotted lines in Fig.' 17) which, near the conclusion of the rotation ofthe break wheels, engages the tail 71 (Figs, 17 and 18) of a wiper 72, by the action of which wiper those tumbler carriers 22 of the register which have turned with the opera? tion of the register, are moved back into line with those tumbler carriers which were held back by the wards 51; (the arrangement of tumblers 44 of the transmitter key device bein such as to free those tumblercarrierswhich turned with the register, once that register has been turned). The register may then be withdrawn from the key device.

It is important that apparatus such as described herein shall be substantially tamper proof; and it is believed that in this respect the apparatus herein described offers a high degree of protection. Normally, access to the tumblers 26 of the register is blocked by the sleeve 27. If this sleeve be pushed back with a view to tampering with the tumblers, the tamperer has still'to learn what particular combination of tumblers is engaging sleeve 23; and if he learns this,

, still it is practically impossible for him,

without special tools, to hold back simultaneously all of the tumblers engaging that sleeve. If, in working over the register, he should press back sleeve 30, as he is very apt to do, and then should press back a tum-' bler holding one of the tumbler-carriers 22, that tumbler carrier will be apt to fall to one side or the other, with its tumbler totally inaccessible, and the register cannot then be inserted into any of the key devices. This'sleeve 30, by-the way, is pushed back automatically as the register is inserted into any of the key devices, and moves out again as the register is Withdrawn. It holds in line all of the tumbler carriers the tumblers of which may not be in engagement with perforations of member 23.

The construction of the key-device, illustrated in Figs. 11-15 inclusive, is such as to make it extremely diflicult to learn the tumbler-arrangement of any particular key-clevice. While a key-device having a stem on which are tumbler-sockets, and springpressed tumblers within those sockets, together with a shell or case for that stem having a way 46 for the reception of the tumblers lugs, is within ourjoint invention, yet the particular construction of key-device shown, involving certain fall-apart features, such as the sleeve 45 by the removal of which the tumblers are permitted to spring out, as illustrated in Fig. 16, the twopart construction-of the base 41, the means for holding the stem 43 in place, and certain other features, are the sole ,invention of R. M. Hopkins, and so are not claimed herein, but in a companion application, Serial Num ber 303,633 filed June 12, 1919.

An important feature of the transmittercontact-combination arrangement is that whlle only one'certain arrangement of contacts permits the transmission of signals, yet the transmitter itself is operative whether a correct combination of contacts has been set up or not. Therefore, the watchman,

hearing the transmitter operate, is not advised whether or not a signal has been sent.

Hence he is not apt to attempt to tamper with the transmitting devices, for any tamperin is apt to prevent the transmission of signa s, bringing his dereliction-to notice immediately.

' In order that the register may be held firmly in place during the transmission of a signal, the case of the transmitter device is provided with a swinging latch 73 which will engage a collar 74 of the register, so holding the latter in place.

In a separate application, Serial Number 329,729 filed October 10, 1919, by R. M. Hopkins, is claimed a register comprising registering means arranged to register by movements by successive stages with respect to locking means controlled by stationary keys external to the register;
